Mount for gunsight

ABSTRACT

A mount for securing a gunsight above the top of the receiver of a firearm, which mount is secured to the receiver by at least one pin which passes laterally through the receiver side walls upon which pin at least a portion of the action of the firearm is also mounted within the receiver. The mount includes a first portion adjacent the sidewall of the receiver which first portion receives the pin, and a second portion overlying the top wall of the receiver, on which second portion the gunsight is mounted.



1. For use with a firearm of the type having a receiver containing an action and at least one laterally extending pin disposed in aligned apertures in the receiver for mounting at least a portion of the action of the firearm in the receiver, a gunsight mount assembly comprising: a. first means for carrying at least part of a gunsight, said first means including a first portion adapted to lie adjacent to a side wall of the receiver and a second portion connected to said first portion and adapted to overlie a top surface of the firearm receiver; b. pin-receiving means on said first means, said pin-receiving means being disposed coaxially with the pin-receiving apertures of the receiver; and c. pin means for insertion through the pin-receiving apertures of the receiver, said pin means being operable to drive the pin out of the receiver apertures while maintaining the action mounted in the receiver, and said pin means further being operable to be received in the pin-receiving means on said first means to secure said first means to the firearm receiver.
 2. The gunsight mount assembly of claim 1, wherein said pin-receiving means is at least one threaded aperture formed in said first means, and said pin means is provided with a threaded end portion for threaded securement to said threaded aperture.
 3. In combination with a firearm of the type having a receiver containing an action, said receiver having side walls provided with aligned openings; a pin passing through said aligned openings in said receiver side walls, said pin being operable to retain at least a portion of the action in said receiver; a gunsight mount having a first portion adjacent to one side wall of said receiver; pin-receiving means formed in said first portion of said mount, said pin-receiving means being co-axial with said aligned openings, and said pin being received in said pin-receiving means to connect said mount to said firearm receiver; said mount further including a second portion adapted to ovErlie a top surface of said receiver to provide a base upon which a gunsight can be mounted.
 4. A gunsight mounting assembly for use with a firearm of the type having a receiver containing a firearm action, and at least one pin extending through aligned apertures in the receiver to hold at least a part of the action in the receiver, said mounting assembly comprising: a mounting plate having a first portion adapted to be positioned adjacent to a side wall of the receiver of the firearm, said first portion including pin-receiving means positioned for coaxial alignment with the aligned apertures in the firearm receiver, and said mounting plate further having a second portion disposed at an angle to said first portion to overlie a top surface of the firearm receiver when said first portion is adjacent a side wall of the firearm receiver, said second portion providing means upon which a gunsight can be mounted above the firearm receiver, and auxiliary pin means for positioning in the aligned receiver apertures to replace the action-holding pin therein while maintaining the action in the receiver, said auxiliary pin means being longer than the width of the firearm receiver to provide a terminal portion which projects beyond the side wall of the receiver and engages said pin-receiving means on said first portion of said mounting plate to secure said mounting plate to the firearm receiver.
 5. The mounting assembly of claim 4, wherein said pin-receiving means is at least one threaded aperture in said first portion of said mounting plate, and said terminal portion of said auxiliary pin means is threaded to provide for threaded engagement between said auxiliary pin means and said mounting plate.
 6. A method of securing a gunsight mounting assembly to a firearm of the type having a receiver with side walls including aligned openings in which are disposed at least one pin for holding at least part of an action in place within the receiver, said method comprising the steps of: a. providing an auxiliary pin and driving said auxiliary pin through the aligned openings in the receiver side walls to displace the action-holding pin therefrom and retain the part of the action in place within the receiver which was previously held in place by the displaced pin; b. providing a gunsight-receiving mounting plate having at least one pin-receiving opening therein, and positioning said mounting plate adjacent to a side wall of the receiver with the pin-receiving opening being in axial alignment with the aligned openings in the receiver side walls; and c. driving said auxiliary pin into engagement with said pin-receiving opening in said mounting plate to secure said mounting plate to the firearm receiver.
